Heat accumulating type heat pump system

The utility model relates to the field of heat pumps. The utility model provides a heat accumulation type heat pump system. Wherein the compressor, the indoor heat exchanger, the throttling device andthe outdoor heat exchanger are sequentially connected to form a first refrigerant circulation loop. A heat accumulator is arranged on the outer surface of the compressor, a second refrigerant circulation pipeline is connected to the first refrigerant circulation loop located between the indoor heat exchanger and the outdoor heat exchanger, the second refrigerant circulation pipeline is connectedto an inlet of the heat accumulator, and an outlet of the heat accumulator is connected with the inlet end of the compressor. According to the heat accumulation type heat pump system, the waste heat of the compressor is fully utilized, the heating capacity of the system is improved, and heating is enhanced. 本实用新型涉及热泵领域，提供了一种蓄热型热泵系统，包括依次连接形成第一制冷剂循环回路的压缩机、室内换热器、节流装置、室外换热器，所述压缩机的外表面上设有蓄热器，位于所述室内换热器和室外换热器之间的所述第一制冷剂循环回路上连接第二制冷剂
